With the news of Peter Murrell’s arrest breaking this morning, spare a thought for Humza Yousaf. Murrell wasn’t just a “proven election winner” for Humza’s party, he was also a “close acquaintance” of the First Minister. Just weeks ago, Yousaf was mulling over plans to keep him in post as the SNP’s exec, saying “anyone that doesn’t want a proven winner on their side, particularly in politics, I think that would be a little bit daft”. Yousaf’s praise for Murrell didn’t end there, he said the arrested SNP chief executive had done “more for our party and our movement than just about anybody else”. Clearly a great loss to the independence cause.
